People wave Turkish flags as they take part in a protest in support of Turkey's position on the 1915 mass killing of Armenians in the Ottoman Empire, at Times Square in New York April 26, 2014. The exact nature and scale of what happened during fighting that started in 1915 is highly contentious and continues to sour relations between Turkey and Armenia, a former Soviet republic. Turkey accepts that many Armenians died in clashes, but denies that up to 1.5 million were killed and that this constituted an act of genocide - a term used by many Western historians and foreign parliaments.
